Lesson notes

Learning Objectives

Indicator: 3.4.1.LI.1 - Apply knowledge of specified statistical analysis methods to analyse the result of experimental studies.

By the end of the lesson, learners can:

Identify the dependent and independent variables in a given biomedical study scenario.
Calculate measures of central tendency (mean, mode and median) from experimental data.
Calculate measures of variability (range, variance and standard deviation) from experimental data.
Construct scatter plots and histograms from study data and explain how changing the y-axis scale can exaggerate or diminish the apparent outcome.
Explain how sample size affects how well a sample represents the larger population.

Content standard: 3.4.1.CS.1 - Demonstrate an understanding and application of a variety of biomedical experimental designs. 3.4.1.LO.1 Use scientific literature and statistics to design experiments and analyse results.
Indicator: 3.4.1.LI.1 - Apply knowledge of specified statistical analysis methods to analyse the result of experimental studies.
Suggested placement: Semester 2, Week 17 (Week 37 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

Structured Talk for Learning: Learners engage in a discussion on the explanation of dependent and independent variables of sample biomedical study. Discuss statistical measures and the effect of sample size on representation of a population.
Activity-Based Learning: Using data from a study, learners calculate measures of central tendency (mean, mode and median) and measures of variability (range, variance and standard deviation). On scatter plots or histograms, learners are tasked to change scales on the y-axis(ordinate) for the plot of the same data and observe how changes in the scale may exaggerate or diminish an outcome
